SPRlNG-HORSESHOE.

SPECIFICATION forming part of Letters Patent No. 643,662, dated February20, 1900. Application filed May 24, 1897. Serial No. 637,823. (Nomodel.)

To all whom it may concern.-

Be it known that I, JOHN MOO. LORD, of Kansas City, Missouri, haveinvented certain new and useful Improvements in Horseshoes, of which thefollowing is a full, clear, and eX- act description, reference being hadto the accompanying drawings, which form a part of this specification.

My invention relates to improvements in horseshoes, having moreparticular relation to providing a horseshoe that shall relieve thehorse from the objectionable and injurious shock incident to travel overpaved streets and hard roads; and my invention consists in certainfeatures of novelty hereinafter described, and pointed out in theclaims.

Figure I represents an isometric View of a horseshoe provided with myimprovements. Fig. II represents a lateral cross-section of the shoe onthe line as x of Fig. I. Fig. III represents a cross-section on the liney y of Fig. II. Fig. IV represents a View of the toe of the shoe,showing the manner of securing the two parts of the shoe together atthat point. Fig. V represents a similar cross-sectionto Fig. III withthe antifriction-rollers omitted. Fig. VI represents a cross-sectionsimilar to that shown in Fig. III, showing a modified form of spring.Fig. VIIrepresents a cross-section showing the recess for the spring inthe outer portion of the shoe.

Similar numerals represent similar parts throughout the several views.

The shoe is formed in two parts, the outer and inner shoes 1 and 2, theouter shoe being provided with the projecting ears 3, arranged to bereceived in the recesses 4 in the inner shoe and fastened by the screws5, the two parts being thereby secured together. In the outer face ofthe inner shoe are formed the recesses 6-a suitable number on eachside-and a suitable distance apart-or, as shown in Fig. VII, therecesses 6 may be made in the outer shoe, and instead of a recess foreach spring a continuous groove may be formed, this being the preferableconstruction. In the outer shoe are provided the openings 7, in whichare arranged the studs 8, provided with,

springs 9, arranged to be received in said recess 6 and bear against theouter face of the inner shoe. 10 represents antifriction-rollersarranged in said recess 6 between the springs and the recess to lessenthe friction of the spring upon the face of the recess. Said springs maybe secured to said studs, as shown in Fig. III, by engagementin a groove11 in the stud, or more simply, as shown in Fig. VI, by a screw 12,passing through the .spring and into the stud, the latter being thepreferable construction. The springs and studs are so arranged that innormal position the stud will protrude a short distance beyond the faceof the outer shoe, as shown in dotted lines, and will by the weight ofthe horse when brought down upon a pavement or hard road be pressed up'flush with said face, in such action the elasticity of the springserving to break and relieve the force and ef fect of the concussionwhen the weight of the horse is thrown upon the shoe on such pave= mentor hard road.

Thus is provided a shoe whereby the in jurious efiect upon a horsetraveling over hard pavements and hard roads is entirely obviated andrelieved against. Such a shoe is of particular advantage to road horsesand trotters which in driving over pavements and hard roads soonbecomestove-up and'stiflened and lose their usefulness by reason of the strainupon the joints, bones, and muscles of the legs and shoulders caused bythe jar and concussion in bringing their feet down upon the hard surfaceof the pavement or road, whereas by providing an arrangement of shoethat will yield to the first impact of the foot, and thus break the jarand prevent the concussion when the foot is brought down, the injuriouseffect is prevented and the usefulness of the horse is prolonged. Afurther effect of such a shoe will be that the resilient reaction of thespring after compression will tend to lift the weight of the horse muchlike the action of a spring-board in jumping, greatly assisting theforward motion of the horse and adding to its speed.

Having thus fully described my improvements, what I claim asmyinvention, and de sire to secure by Letters Patent, is-

1. A horseshoe consisting of a hoof-plate provided with recesses 4 and6, a track-plate provided with openings 7 corresponding with saidrecesses 6 in the hoof-plate, lugs 3 on said track-plate arranged toengage said recesses 4 in the hoof-plate, and spring-studs arranged insaid recesses 6 in the hoof-plate and protruding through said openings 7in the track-plate, substantially as set forth.

2. A horseshoe consisting of an inner and outer portion, recesses formedin the shoe between said portions, a series of studs arranged insuitable openings in said outer portion, a series of springs connectedwith said studs arranged in said recesses, and antifriction-rollersarranged between said springs 10 and said inner portion; substantiallyas and for the purpose set forth.
